IMPROVEMENT lil CENTRlFUGL M/lCHllN'lS FOR i.iQUORlNG HA'liD SIICAR.

Specification forming part of Letters Patent No. 2h L, dated February 4, 1879; :application filed July 2, 1878.

To all whom 'it may concern Be it known that l', WALTER l. Entien- IIORs'r, of Jersey City, New Jersey, have invented a certain. Improvement in Centrifugal Machines for Liquoring Hard Sugar, of which the following is a speciticatiou:

My improvements relate to apparatus for liquoring' hard sugar by centrifugal force; and the general nature of inyinvention consists in the combination, with the series of molds of a centrifugal iiiachinc, of a like series of pairs of radially-arrangcd partitions, joinedat their tops and bottoms, and a central reservoir provided `with a spout for cach mold, by means of which liquid from the reservoir is conducted into the spaces between the partitions, and immediately opposite the inner sides ofthe molds, and therefrom is forced by centrifugal action into the sugar contained in the inold, the central reservoir being,` divided by radial par-ti ti ons into as inany compartments as there are molds, for the purpose of insuring,r the discharge oi equal quantities 0i' liquid by ail the spouts. 1

My invention, also includes thc uniting of the two radial partitions required for each mold iii the form of a boit provided at its upper end with a chiite, and in. combining,` a number of such boxes corresponding with the number or" molds contained in the machine with mechann ism whereby' the boxes, the edges ot" which are faced with an elastic gasket or packing, are simultaneously pressed against the inner edges of the molds, for the purpose of niaiiing tight joints between the molds and the boxes.

Finally, my invention includes the speciiic construction of the mechanism for forcing the boxes against the molds, which is heroin shown and described.

The accoiii'panying drawings, representing;` a centrifugal machine containing inyiniprovements, are as follows: Figure l is a top-view oi' one halt' of the machine, the other half bcing shown in transverse section on the line c fr in Fig. 2. Fig. 2 is a central vertical sec tion ot' tlic machine. Fig. 3 is a transverse section thereof through the line g; y on Fig. 2.

My centrifugal machine, has thcfnsual baskot A, provided with the perforated rini A'. I. arrange on the inner side of the rim a series plcyed in opening an umbrella.

in g' mechanism consists oi' a sleeve, H, whiclr is made to slide on the spindle l by means of of Vertical pillars, B, which are equidistant, and which serre as guides to hold the cuter cornersio' the 'sugar-molds Q.

Immediately opposite the inner side of each mold is a box, D, the edge. i' which conforms to the shape ol the inner edge of the mold, and is covered with an elastig'askemO. The u1, per end of this box is provided with an open ing; for loosely receiving; the lower'portion ol' a spout, E, fixed to the bottom of one of the chambers E of the central reservoir, F, which is centrally supportedA above the spindle of the machine.`

The reservoir is divided by the radial par titions F into a number of chambers corresponding with the number of molds iii the machine. y

When the molds are in position the liquor-` in g-boxes are all forced simultaneously out `ward, so that their `edges make tight joints with the inner edges of the molds, by means.'

of spreading mechanism similar to that -einlfhis spreadthe adjusting-screw J.

The lower portion of the ad i'iistiiig-sorew is a lube, J1,ha\'ing a female thread, j,- cut on theinside ol' it, which engages a male thread, j', cut on the upper portion of the spindle.

.ilie lower end ot' the tube J is provided with a laterally-projectiiig flange, J2.

The upper end oi' thesleeve H is held against the end ot'the tube J1 by means of the annularca i lll havin@ an inside 'dance H2 which l i e t i i.

nulas, L, is slipped on the lower 'end of the sleeve ll, and held up against the shoulder h by the nut lt will thus be seen that the transverse pii'- I ots on the inner ends of the spreading-arms 'spouts; secondly,

\ K have their bearings, one half in the recesses in the shoulder h, and the other halt' in corre- K is forked, and embraces apivot, d, inserted in the ears d' on the inner side of onev of the boxes D, the ferkedend of the arm K being secured to the pivot d by thel vertical pin d.

The range of movement of the sleeve H is limited by means of the key-screw M, the inner end of which projects into vthe groove M', formed longitudinally in the spindle I. It will be seen that by turning vthe actuatingscrew J the sleeve H may be lowered or raised, and the boxes D accordingly either simultaneously thrust outward against the molds or drawn inward away from the molds.

.In applying my improvements to centrifugal machines provided with the ordinary molds now in use, I find it convenient to employ boxes closed on the side toward the spindle f the machine, and to provide the inwardlyprojecting chutes e to receive the ends of the spouts E instead of making a hole for the purpose in the top l)2 of the box.

The sides D, tops D?, and bottoms D3 of the boxes constitute detlectors and guides, which serve to insure the discharge of all the liquor from the boxes D, respectively, into the sugar contained in the molds with which the boxes are respectively in contact. partitions Ii" in the reservoir serve to insure an equal discharge by all the spouts of the liquor introduced into the reservoir.

It will, of course, be understood that various forms of mechanism may be employed to press the boxes and molds closely together, so as to make a tight joint between them-as, for example, the boxes may be stationary and the molds maybe pressed inward against the boxes; or, the molds being stationary, the boxes may be pressed outward by means of cams instead of spreadin g arms. I prefer, however, the form of mechanism for this purpose which is herein described.

I am aware that various attempts have been made to liquor hard.J sugar in the centrifugal machine; and I do not,therefore, claim broadly apparatus adapting centrifugal machines to such a purpose, the distinguishing features of my invention being, first, the central resei'voir provided with a spout for each mold, with radial partitions for insuring the discharge of equal quantities of liquor through all the y the boxes D, thel material parts of which are the sides Dl, which are radial partitions, and the ends or -top D2 and bottom D, which are horizontal partitions, the' sides and ends answering to deflect and guide into the sugar-molds all the liquor injected into the several spaces within the defleetors and behind each sugar mold, respectively, such spaces being the receiving-chambers D4.

I claim as my invention in apparatus for liquoring hard sugar in the centrifugal machine- The radial l. A central reservoir for containing the sugar liquorA divided by radial 'partitions into compartments of equal sizes, and provided with a downwardly-projecting spout from the bottom of eaeljcompartment, substantially as and for the purp e set forth.

2. The 'sugar-m lds provided with the vertical deilector-plates D1 and horizontal plates Dz and D3, in combination with a central reservoir,-.for the purpose of effecting an equal distribution to each mold of liquor discharged from the central reservoir.

3. The combination, with each mold, of deectors or guides on the inner side of the mold and a spout projecting downward from a eentral reservoir divided by radial partitions into a number of compartments equaling the number of molds in the machine, for thel purpose of conducting all the liquor discharged from any compartment of the reservoir into the mold immediately opposite the spout connected with such compartment.

4. A seri s of molds coneentrically arranged in the bask t of a centrifugal machine and an inner circleofliquor-distributin g boxes,in combination with adjusting mechanism mounted upon the machine, for thepurpose of simultaneously moving all the boxes either inward or outward on radial lines, substantially as and for the purpose set forth.

5. In a centrifugal machine for liquorin g hard sugar, the combination of the mold U with the liquoring-box D and the packingstrip C', for the purpose of making a tight joint between the liquoring-box and the mold, substantially as described.

6. The boxes D, provided with the chutes c and with the elastic gasket C', in combination with the sleevevH and t-he radially-arrj.'mged spreading-arms K, constructed and operating substantially. as and for the purpose set forth.

7. The sleeve H, provided with a projecting shoulder, h, notched and recessed, as shown and described, in combination with a notched and recessed annulus, L, and a nut, I, as and for the purpose set forth.

S. ln a centrifugal machine for liquoring hard sugar, the reservoir F, provided with the radial partitions F and the spouts E, the boxes D, provided with the chutes e, the elastic gaskets C', and the ears dl, the spreadingarms K, each provided at its outer end with.

a transverse pivot journaled in one of the pairs of ears d, and at its 'inner end with a transverse pivot journaled in a central sleeve, the sleeve H, traversing a portion of the spindlel, and the actuating-screw J, engaging a screw-thread cut upon the spindle I, the whole arranged and operating lsubstantially 'in the manner and for the purpose set'forth.
